Dear HA
Hello!
I'm from Poland, and I would like to see polish transaltion, and I really want to create it! That will be so much fun helping transalting a game! And if I will transalte, will I get somekind of a reward? I don't really need a reward, but if I could get one : I will want hero selection xD . I don't know wich one is the best xD
